Mitosis only
OPTION A
Mitosis is simply the process of cell division.
Meiosis is the
process of producing gametes (eggs and sperm), which is important for sexual reproduction.
The correct answer is: The synaptonemal complex.
Non-sister chromatids are chromatids from two homologous chromosomes. In prophase I of meiosis two homologous chromosomes pair and this pairing is called synapsis. This allows possible crossing over to occur. Two non-sister chromatids are connected in synapsis by a protein-RNA complex called the synaptonemal complex.
Crossing-over or the physical exchange of chromosome parts might occur and bring to genetic recombination. The sites of crossing-over between nonsister chromatids and are called chiasmata.
Answer:
Cell Z has the greatest solute concentration
Explanation:
- The water moves from higher potential to lower potential.
- More the solute concentration in solution the lower will be water potential.
- External mechanical pressure increases the water potential.
Cell Z has more solute concentration, So it require more external pressure to equalize its internal water potential with external water potential for stopping the movement of water from high potential to lower potential.
<em>Remember the maximum potential of water is zero at standard temperature and pressure.</em>
Answer
0° C or 273.15 K or 32°F
Explanation
The ordinary freezing point of water is 0 degrees Celsius. This is also the melting point of water.However,when there is presence of impurities in the water, the freezing point depression occurs.In some conditions,water can remain in liquid state at -40 to -42 ° F.
